readline.so的问题

apt-get install php5-readline
php5 -i |grep Readline
Readline Support => enabled
Readline library => EditLine wrapper
1.这个EditLine wrapper究竟指哪个library?
2.如何开启readline.so?

find / -name 'readline.so*'
/usr/lib/php5/20131226/readline.so
/usr/lib/x86_64-linux-gnu/libreadline.so
/usr/lib/x86_64-linux-gnu/ruby/2.1.0/readline.so
/usr/lib/x86_64-linux-gnu/libguilereadline-v-18.so.18
/usr/lib/x86_64-linux-gnu/libguilereadline-v-18.so
/usr/lib/x86_64-linux-gnu/libguilereadline-v-18.so.18.0.0
/usr/lib/python2.7/lib-dynload/readline.x86_64-linux-gnu.so
/lib/x86_64-linux-gnu/libreadline.so.6.3
/lib/x86_64-linux-gnu/libreadline.so.6

我想让php开启/usr/lib/php5/20131226/readline.so，应当如何做？
